I've been wanting to start adding some of this to my stash. I see SGammo has the 77 and 69 grain. Which one would be better for HD? I have several different ARs all are 1:7.

I like SGammo and I have placed several orders there but I also like my money. Wideners is cheaper on the 77gr IMI.

I've never ordered from Wideners before but have almost exclusively used SGammo. Super fast shipping and have never had any issues. I know there are probably alot of places out there that are great complanies but I'm loyal to SGammo. I think I'm gonna order up 100rnds of each and test them out. |

While neither business has been an issue for me I understand why you have made your choice. The difference in cost between the two for me is Wideners over SG. It happens often with other items and other vendors; when the cost of shipping alone has been a deal breaker. I'll check this forum in future to see if you provide an update on the performance. Good luck and have a Happy New Year |

Wow I thought this thread was about IMI 69 grain vs. 77 grain razorcore, not Wideners vs. SG ammo.
So I guess I can't ask if the IMI 69 grain is a SMK with or without a cannelure. |

I've shot a bunch of the IMI 77 grain razor core out of my SBRs(10 and 11.5 inch barrels) and get little itty bitty groups(under 5/8 inches at 50 yards with open sights). So I'm very happy with it. Looking forward to 69 grain review. |

What's the difference between the IMI Razor core and BH 5.56 77 gr SMK?
Other than price and availability? |
|
[#12]
Razor Core 77 is sealed and crimped and loaded with ball powder. In my experience IMI brass is softer than LC. No over pressure signs so far but showing brass on the bolt face and lots of small flakes. I don't know about the BH ammo.

[#13]
If it's windy and you're going to shoot out past 400 yards, 77gr all the way.
If not, the 69 is fine and may be a little more accurate. I've taken the IMI MK262 clone out to about 900 yards and was able to hold a 14" group out there. 10 round group, shot off a bipod with a 10X scope. |

Unfortunately the indoor range I go to only has a max distance of 25 yards. I was planning on using these rounds for HD. All I have now is IMI M193 or IMI 62gr green tip rounds. Just buying boxes of 20 rounds and testing them.

Use the M193. I wouldn't waste MK262 on anything under 200 yards. It's just gettin' warmed up at 300M !

I picked up several thousand rounds of assorted soft point Ammo a few years ago but reading here had convinced me that I had chosen poorly. Thank goodness I never sold it! I was about to buy a few thousand rounds of 77gr IMI too. Might still get some for dedicated SPR use but now I'll have to see what quality sp I can find on sgammo |

I did find some suitable HD rounds in a forgotten ammo can. I found a few boxes of black hills 5.56 50gr TSX and Speer 64gr GDSP Rem .223. rounds. I also found and fired BHA 69gr SMK Rem .223 rounds at 25 yards with my 16" 1/9 twist barrel. I did buy some IMI 5.56 69gr Razorcore at Cabela's so I am going try firing a few boxes on next trip to range.
